I made my brief introduction to the 996 forum when I purchased by C4S from Colorado a few weeks ago and drove it back to Charlotte. I thank those who helped me along the way. It was quite an adventure and a great way to learn about the cars capabilities. For those who didn't follow the thread, here is my car as I know we all like pictures:
Front
My best side
Love the seats
With that out of the way, I have been doing DE's for the past 15 years. I know how to set up a rear drive 911 but as this is AWD I am going to try and resist doing too much to this one initially (I am already wondering how it would handle with KW Clubsports) but my first question is specific to the 996 engine. This car already has the IMS/RMS/Low TEMP Thermostat. Should I consider a Deep Sump Kit that LN Engineering sells prior to taking her on the track? Other suggestions as preventative engine maintenance is welcome.
My second question is to setup. I figure I will start with street tires (Michelin Pilot Sports) and the current suspension is the Euro M030 setup with H/R bars. Brake pads are stock as is the fluid and I do plan on replacing the fluid to high temp and different pads. The track will be VIR so it is high speed but does have a few significant braking zones. How do you guys set up your bars assuming they are adjustable?
I am daily driving the car and it is a complete joy every time I start her up. All of a sudden, I am very willing to take the long way home.

Oiling under high G's is not optimum with these engines. A deep sump kit with improved baffling to 1) hold more oil; and 2) hold the oil better around the pick up; has to be pretty high up the list of track mod's.
IIRC the LN Engineering deep sump kit comes in for high praise so the kit might be the way to go.
You should show up at the track with fresh oil too.

You'll likely be fine on your street tires, however for a bit more peace of mind I do recommend following Macster's advice and installing a deep sump kit/baffle.
The FVD Kit works well and is a very high quality item.
If you PM Rhonda@FVD you may get a Rennlist discount.
+1 on the baffle. I went with FVD but LNE is really good as well. I was worried a 2L deep sump would put the oil pan too low so I went with the .75L sump. Make sure you have an oil in that can handle the heat has well.
For the C4S, in think Vandersmith ran 3rd hole front and rear (middle for front, 3rd stiffest in rear.) The clubsports would be awesome if you are going to track it quite a bit. They have much better spring rates than the V3s. They will also be alot harsher for daily driving. Eventually you will want to drop the front diff and go rear wheel drive if you want better feedback and quicker times. AWD and PSM are really good if you are worried about walls or want a little more leeway to make mistakes though.
Look at other tires like RE-71, RE-11, Dunlop Star Spec, Hankook RS 3. They are all better street tires for tracking.
Thanks for these, I will see if they come in WB sizing. My initial thought was to see how well the Michelins worked and then go to a more aggressive tire, should I not like them on track.

Don't know about Pilot Sports, but Pilot Super Sports sometimes tend to chunk when abused on track.

Just keep it under 0.8 G and it will be fine.
Someone quoted that number from some Porsche literature on another thread. I think from an interview with Harm Lagaay, Pinky Lai or..?

But this car with decent tires will approach 1.5 G. A good deep sump will cover that.
all seriously good advice thus far. Some things to consider, how many miles? Might want to replace the water pump. Also, if your car smokes at start-up, give some consideration to replacing the AOS with the Motorsport version. Pricey(er) but well worth it. I suspect that the extra weight of the AWD will add to brake pad usage as you try to haul that baby down before turning in......consider brake fluid change (as previously mentioned) also, might want a higher performance brake pad. some like Pagid, some like Ferrodo(?), some like PFC (I tired them, no bedding in, but the dust welded to my rims and ruined the finish), there are others, too (Hawk, Endless?).
I hate to mention this, as the topic has been covered ad nauseum, has the IMS been addressed???
GL, enjoy the new baby, if you are running at VIR with N Carolina, say hello to Alex Bell for me please....... have a blast!
